United Macedonia (Macedonian: Обединета Македонија, romanized: Obedineta Makedonija), or Greater Macedonia (Macedonian: Голема Македонија, romanized: Golema Makedonija), is an irredentist concept among ethnic Macedonian nationalists that aims to unify the transnational region of Macedonia in Southeastern Europe (which they claim as their homeland and which they assert was unjustly divided under the Treaty of Bucharest in 1913) into a single state that would be dominated by ethnic Macedonians. The proposed capital of such a United Macedonia is the city of Thessaloniki (Solun in the Slavic languages), the capital of Greek Macedonia.
